Handles coding of MIME "x-www-form-urlencoded".
This class handles the encoding and decoding for either the query string of a URL or the _content of a POST HTTP request.
Notes
The UTF-8 charset is assumed, unless otherwise defined by either passing a parameter or setting the "org.eclipse.jetty.util.UrlEncoding.charset" System property.
The hashtable either contains String single values, vectors of String or arrays of Strings.
This class is only partially synchronised. In particular, simple get operations are not protected from concurrent updates.
